New hardware for graphic work computer

Hello,

I'm a graphic designer who has just convinced my boss to buy me a new work-computer. But I don't really know what to get for it (I'll be putting it together myself). I asked a computershop, and they gave my this recommendation:

I'll first and formost be using it for Photoshop, Indesign and Illustrator. BUT I'll soon be working with video also, so it really need to be able to handle Premiere and After Effects. (I did some videoediting last year, and my current work-computer could NOT handle the workload at all!)

It'll be running from an SSD, and files will be stored on the hhd (the second hhd is for internal backup).

Is the grahic card up to speed? Anything I should change? More RAM? Anything?

I hope to get a little helt. Thank you.
